Pivotally connected to the aperturedears 2'! and 28 by means of the pins 29 and 30, respectively. are thecomplemental links 3| and 32 which are arranged in spaced, parallel,relation with respect to each other. The ends of the links 3| and 32 arepivoted to the legs 33 and 34, respectively, of the support 35, andsecured to the support 35 is the rod 36, said rod being held in side byside relation with respect to the mop handle ID for sliding movementtherealong by means of the clamps l1 and I8, and for sliding the rod 36and supports 35 longitudinally along the mop handle III, the actuatinglever 31 is secured to the rod 36.

Secured to each end of the transverse bar 26 is a guide link 38 and 39,the link 38 having one end pivotally connected to the arm 20 of theframe [9, by means of the pin 40, and the link 39 having one endpivotally connected to the arm 2| by means of the pin 4|. Journaled inthe other ends of the links 38 and 39 is the shaft 42 and rotatablymounted on the shaft 42 is the upper or first roller 43, coated withrubber or other suitable material. The first roller 43 is positioned onone side of the mop cloth l2, and

positioned on the opposite side of the mop cloth 7 I2 is the second orlower roller 44 rotatably mounted on the shaft 45, the shaft 45 beingjoumaled in the links 46 which are arranged in spaced, parallel relationon each side of the frame l9 and formed integral with the arms and 21,Figures 4, 5 and 6. The roller 43 is normally biased towards the roller44 by means of the springs 41 and 48 arranged on opposite sides of theframe l9, the spring 4'! connecting the movable link 39 to the fixedlink 45, the coil spring 48 being similarly connected on the other sideof the frame l9. 7

The operation of the mop and wringer is as follows: The mop cloth I2 ismade fast to the mop cloth holder ll of the mop handle [0 by means ofthe spring l3 and hand hold [4. With the rollers in the position ofFigure 1, the mop cloth is immersed in a pail of water or cleaningfluid.

After the mop cloth l2 has been dipped in water it may be very quicklyand easily wrung out by grasping the lever and moving it towards theclamp l1, thus causing the rods 22 and 23 carrying the frame l9 to bemoved along the mop. As the frame I9 is moved, the upper and lowerrollers 43 and 44 are moved along the mop cloth l2 to thereby squeezethe water from, the cloth I3, the rollers being positioned as shown inFigure 4 at the completion of this step. After the water has beensqueezed out of the mop cloth I2, the lever 25 is moved forwardly fromthe position shown in Figure 4 to the position shown in Figures 5 and 6,such movement causing the links 3| and 32 which are operativelyconnected to" the transverse bar 26 to pivot the upper roller 43 out ofbearing engagement with the mop cloth 12 since the arms 20 and 2| of theframe l9 will be moved forwardly, while the links 31 and 32 of thesupport 35 have their forward movement stopped by the lever 31 bearingagainst the clamp [1. With the upper roller 43 in this raised, out ofcontact position, the levers 25 and 3'! are moved away from the clamp I!to thereby return the frame and wringer assembly to the position ofFigure 1, the lever 31 being released as soon as the mop cloth I2 isclear of the rollers, and the mop is ready to be used for moppingpurposes. While the mop cloth I2 is being wrung out, the mop willpreferably be held in a generally upright position over a mop pail orlike receptacle.

In view of the foregoing description taken in conjunction with theaccompanying drawings it is believed that a clear understanding of theconstruction, operation and advantages of the device will be quiteapparent to those skilled in this art. A more detailed description isaccordingly deemed unnecessary.-

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention the same issusceptible to certain changes fully comprehend by the spirit of theinvention as herein described and the scope of the appended claims.

- Having described the invention, what claimed as new is:

In a mop including a handle, a holder, and a mop cloth releasablycarried by said holder, the improvement consisting of providing awringer for squeezing water from said mop cloth, means operativelyconnected to said handle for actuating said wringer, said wringercomprising a frame having a pair of elongated symmetrical arms, a firstpair of spaced links secured to the ends of the arms of said frame, afirst rotatable roller arranged in abutting relation with respect to oneside of said mop cloth, and carried by said first pair of links, asecond frame positioned above said first frame and having legs ofshorter length than the arms of said first mentioned frame, a secondpair of links pivotally connected to the arms of said first frame, asecond roller rotat-.

ably carried by said second pair of links mounted for movement towardand away from the other side of said mop cloth, resilient means embody-.

ing a coil spring connecting the respective first and second pair oflinks together for biasing said second roller toward said first roller,and means on said handle for moving said rollers away from each other,said means comprising said second frame, and said second pair of linksbeing operatively connected to said second frame.
